CONTAINER Filed April 16. 1929 4 l l, n Imm l 1 l III Illllll llllm Patented -May 5, 1931 UNITED STATES PATENT OFFICE CONTAINER Application led April 16', 1929. Serial No. 855,548.

This invention relates to that type of container which is adapted for the packaging ofice-cream or the like and to special improvements therein.

A primary object of this invention is to provide a container which, due to its special construction, will keep ice-cream or the like in a solid or frozen condition over relatively long periods of time.

Another object of this invention is to provide a package which consists of an outer container, an inner container which receives the article to be preserved, and also a metal box containing solidified CO2 or the like together with means for allowing free circulation of the refrigerated air around the article to be preserved.

Other objects and advantages will become apparent during the course of the following description wherein I have described a preferred embodiment of my invention and in which;

Fig. 1 is a vertical central section of a package embodying my invention, and,

Fig. 2 is a horizontal view taken on the line 2-2 of Fig. 1.

Referring to the drawings wherein like reference characters are used to designate like parts throughout vthe several views: The letter A represents generally my improved package, which is formed with an outer container 3 and an inner container 4. The inner container 4 may be provided on its outer surface with corrugations 5 .which engage the outer container 3 and serve to form air spaces between the two containers.

The bottom of the inner container as shown, is formed with two walls 6 and 7, the wall 7 being provided with corrugations 8 and 9, the corrugations 9 providing dead air chambers between the two walls 6 and 7. The outer wall 6 of the bottom is provided with an integral upstanding flan el() which is secured to the side wall of t e inner container 4 as at 11 b gluing.

4It willV e seeny that the outer container 3 is ressed inwardly at its upper end and secured y gluing to the inner container as at 12, while the lower end of the container is glued to the flange 10 of the bottom 6 as at 13 thus to CO2 forming a completely sealed dead air space between the walls 3 and 4.

Positioned within the inner container 4 is a tube of longitudinally corrugated paper or cardboard 14 within which is positioned the package of ice-cream or the like 15 which it is desired to preserve. The tube 14 may be of saw tooth formation 'so that when a package which may be of rectangular or v.square formation in transverse section, and of pro er dimensions, is positioned in the tubetle longitudinal edges of the package will enter certain valleys of the corrugations and thereby'prevent rotary `movement of the ackage wit in the container. This action, o course, will be true to a certain extent if the corrugations are of rounded formation. A metal or the like container 16 is received within the tube 14 which may contain solidified CO2 as the refrigerating medium. This container is provided with protuberances or corrugations 17 on its upper and lower surfaces for the purpose of providing air spaces between itelf, the ice-cream package 15, and the cover The cover 18 alsois provided with double walls 19 and 20, the wall 19 having a downwardly extending integral liange 21. This flange 21 has its lower inner face coated with a dry glue which may be moistened at the time of being placed on the container so as t0 secure the cover securely to the container as shown at 22.

The sublimated gas from the solid CO2 in the container 16 may escape through the joint which connects the two complementary parts of the container and then through the crevices which may exist at 22 or through the walls of the outer jacket which may be porous It be seen from the foregoing description that I have provided a container which is double walled on the top, sides and bottom so as to provide dead air insulating spaces at these points and that there is allowed a free circulation of the refrigerating medium on all sides of the package 15 due to the fact that the refrigerant container is spaced from surrounding surfaces by the protuberances or corrugatlons, 17, and by the tube 14, while the ice-cream container 15 is spaced by being supported by the corrugations 8, the tube 14 and the beforementioned corrugations 17. However, it is to be understood that various changes may be made without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. In a container of the class described, a bottom wall provided with internal corrugations, a refrigerant container positioned within said container, said refri erant container being provided with protu erances on its upper and lower surfaces, and a package mounted within said container and resting on said corrugations.

2. A container for ice-cream packages having positioned therein a refrigerant container, said container being provided with 11pper and lower protuberances to provide spacing means, a cover for said container engagin said upper protuberances, said lower protuerances resting on an ice-cream package positioned beneath said refrigerant container.

In testimony whereof I aiix my signature.
